Paul Drayson, a former British science minister, has developed a device that captures “electrosmog” (invisible clouds of electromagnetic radiation), and uses it to power small devices. The energy-harvesting system is known as Freevolt. Freevolt uses an antenna to gain power from multiple wavebands of the electromagnetic spectrum. This is the first commercial device that is … [Read more...]
High School Students and UPenn Professor Build Radio Telescope in West Philadelphia
This past summer, as part of UPenn’s Summer Science Academy Program, 12 high school students along with James Aguirre, associate professor in the School of Arts & Sciences’ Department of Physics and Astronomy, turned an out-of-service TV satellite dish on the roof of the Enterprise Center in West Philadelphia into a 30-foot radio telescope.

India Launches Space Observatory into Orbit to Study Electromagnetic Spectrum
On Monday, Sept. 28 at 12:30 a.m. EDT, The Indian Space Research Organization (ISRO) successfully launched seven satellites into orbit from the Satish Dhawan Space Centre (SDSC) in Sriharikota, India. One of the satellites is the country’s first ever space observatory. This mission, known as PSLV-C30, lasted about 23 minutes and 32 seconds. “The most important passenger of the … [Read more...]
First U.S. Public School District Limits Wi-Fi Radiation Exposure
Ashland, Massachusetts Public Schools have announced they will be reducing Wi-Fi radiation exposure to students and teachers via Wi-Fi Device “Best Practices.” “Spurred by parent Cecelia Doucette's concerns about the lack of safety data on Wi-Fi and children, the district investigated the issue and developed a policy to substantially reduce wireless exposures to students and … [Read more...]
Ground-penetrating Radar Uses Electromagnetic Radiation to Reveal ‘Super-Henge’
With the help of ground-penetrating radar, researchers have discovered that there are 90 large stones, known as Durrington Walls, hidden underground in a village near the famous Stonehenge monument in England. Archaeologist Vince Gaffney and his team announced this discovery at the British Science Festival in Bradford, England earlier this month. “Durrington Walls is about … [Read more...]
Canadian Police to Receive New Radio System after EMI Issues
Sault Ste. Marie Police are preparing for a new radio system, since their current system, which is 15 years old, experiences communication problems and constant radio frequency interference. However, police dispatchers still have problems ahead. “Motorola is phasing out support the console's main components. The withdrawal of assistance starts in 2016 and ends in 2018,” … [Read more...]

Magnetic Field Cloak to Assist MRI Scanners and Medical Industry
Scientists from the Autonomous University of Barcelona have created a magnetic field cloak, or ‘wormhole,’ which could lead to better MRI scanning. “The wormhole allows a magnetic field to be transported across space but it is not the kind of cosmic tunnel popularised by science fiction. Rather, the magnetic field at one end of the wormhole appears at the other end as an … [Read more...]
